Flooding comes to mind.
Next time it does it ....try holding full throttle and crank
continuously to see if that gets it to clear out and fire up.

temp sensor II comes to mind.
Leaking injector is a possibility.
Would be good to know what the fuel pressure is when it does it.
Generally, I don't think I've ever really seen lack of resisdual pressure.
Fuel pressure gauge is a very handy tool to have.
Plus check throttle switch is making contact at idle.  I've found dozens
of those not working right.
